Daedalus

Daedalus is one of the characters from the Sora no Otoshimono series, she is one of the creators of Angeloids that appear throughout history.

Daedalus is the creator of Ikaros, Nymph, the Harpies, Astraea, and Oregano (probably), the 1st generation Angeloids. She frequently appears in Tomoki's dreams as a lover, but she flies away, leaving Tomoki crying. She comes to his dreams to ask him to help save her. Throughout the series, Daedalus sends each of her 'daughters' down to Sorami City with Tomoki, claiming that they have been 'captured by the sky' in hopes that the first generation Angeloids can be freed. Little information is given on her, as well as her relation with Tomoki. Her name originates from the Greek mythological character Daedalus, the father of Icarus. She frequently works with Sugata when he is visiting Synapse. Also, Tomoki (if he is really in a sleeping booth in the synapse) may have either blood or marital connections to Daedalus, because of the way she treats him (hugs, strong concern for his well being and she calls him Tomo).
